Different letters indicate significantly different values (p ≤ 0.05). All values represent the mean of triplicate determinations, mean ±SD (n = 3). L*, a*, b*, ΔE values are standards of color measurements. L* refers to lightness ranging from 0 to 100, a* refers to green to red, and b* refers to blue to yellow. WHC, water holding capacity (g water/g hydrolysate). OHC, oil holding capacity (g oil/g hydrolysate).
